1" `1)"*A' s'ailine concentritt'e derived yfrom i salme-'leken the West,- in which potassium 36; kiln-.to ,produce ,s line concentrate which.

As' ai1ex-mple ofthe proportions in which the above' substnces are combined the following isgiven, but. itA is understood the proportions may be somewhat varied: 300

46 pounds of saline concentrato is dissolved in water to 30 B., thereby forming n brine containing some solids which are removed by filtration. Solutions of the renminng constituents are pre ared as' follows: 3 0

60 pounds of calcium ch oride in hot water toY a 10 B. solution, 20 pounds of magnesium chloride in cold water to c, 10 B. solution,

10 pounds of alum in three gallons of boilposs-imam proceed-wiwi mais the application o a water, o

cleaned with a suitable acid solution apro rately diluted, for example, nitric acid,

y rochloric acid or sulphuric acid. The surface is then flushed with clean water and a suitable amount of the undiluted co1nposition of matter applied thereto. The-coniposition of matter may be applied b a p is tering brush or by means of a sma l sp nkling can. The bottom 'concrete surf ce, treated as described, is ready to receive he to -mixtuife The top-mixture is mixed with a .dilute solution of my compositie of matter, preferably one part of the sam to 10 parts of iiiater. It has been found t at concrete bonded with my com osition of matter in the manner deseribedurnishes a thorough and efficient bond, without the use of any ,neat cement or gro'uting, and penetrates the concrete base to at least a epth of one-quarter of an inch. My composition of mattei' may be applied as a finishing agent to a concrete surface to give it a high polish. It may be applied Vto the filial troweling mixture b sprinklingl thereon a suitable amount of t e undiluted substance. After the troweling has been continued until the composition of matter is absorbed in the cement surface, the latter, in appearance, resembles highly olished marble.

My com sition of matter, suitably diluted, is a apted for use in stucco work. The stucco work is to be done in the usual fashion, two coats of cement and sand mortar. After the scratch coat hasbeen ap plied to the laths, and the former allowed to dry over night, it is essential that the scratch coat be treated with a suitable quantity of my undiluted composition of matter before the final coat and the stone dash or granite chips which are to be applied to the nish-coating, while the latter is in a plastic condition. The composition of matter is preferably applied to the finishcoatng by spraying.

Cement fioorsQmay be treated with my composition of matter by dissolvin one part of the same. in five parts of water. position may be ap lied bysimply flushing it on the' surface o the cement floors. The composition dries after about thrt minutes penetrating the concrete pores an forming i and acid-proofeurface, thereby he canal-the saline reventing disintegration and L'In reduction to practice, I have found that J 1 the composition necessary in the carrying of my invention into effect-und referred to in the above description is the moet effective.,`

Yet realizing that tlicxconditions concurrent with the cari' 'ing of my invention into use will necessari y vary, I desiic to emphasize the fiit that certain modifications and changes in the elements and steps may be executed when necessary without sacrificing any of the advantages of my invention as defined in the appended claims. Iclami 1. A hardening and bonding coinpositin adapted for the treatment of concrete n d cement comprising the reaction-productsresulting from a mixture of a saline concentrate, magnesium fiuosilicatc,calcium chloride, magnesium chloride, alum, zinc sulfate, barium sulfate und iron oxide, the saline concentrate being present in the mixture in a predoinin-.iling amount and the remainder of the constituents in aniounts greater than traces.

2, A hardening and bonding composition adapted for the treatment of concrete und cement comprising the reaction-products rcsulting from a mixture of a saline concentrate from which the solids have been rcrnoved, magnesium. fluosilicate, calcium chloride, .magnesium chloride, alum, zinc sulfate, barium sulfate, and iron oxide, the saline concentrate being present in the mix- .ture `1in a predominating amount and the remainder of the" constituents in amounts geater than traces. y

l, A hardening and bonding composition a apted for the treatnient'of concrete and cement comprising the reaction-products re- `illting from a mixture of a'saline concenrate containing a substantial ortion of potassium salts, inagnesiuin uosilicate, calcium chloride, magnesium chloride, alum, zinc Sulfate, barium sulfate and jion oxide, concentrate being prsent inl the mixture in a predominating/amount and the remainder of the constituents in amounts greater than traces.
